Here is a very small sampling of some quotes that I have collected:

What can we gain by sailing to the moon if we are not able to cross the abyss that separates us from ourselves? This is the most important of all voyages of discovery, and without it, all the rest are not only useless, but disastrous.
 —Thomas Merton

Concerning all acts of initiative, there is one elementary truth the ignorance of which kills countless ideas and splendid plans: the moment one definitely commits oneself, then Providence moves too.  All sorts of things occur to help one that would never otherwise have occurred.  A whole stream of events issues from the decision, raising in one’s favor all manner of unforeseen incidents and meetings and material assistance which no man could have dreamed would come his way.  Whatever you can do or dream you can do, begin it.  Boldness has genius, power, and magic in it.  Begin it now.
 —Johann Wolfgang von Goethe

Let us not look back in anger or forward in fear, but around in awareness.
James Thurber

One person with a belief is equal to a force of 99 who have only interests.
John Stuart Mill

We could never learn to be brave or patient, if there were only joy in the world.

Most powerful is he who has himself in his own power.

What lies behind us and what lies before us are tiny matters compared to what lies within us.

Whenever you see a successful business, someone once made a courageous decision.
Peter Daucher

Take time to deliberate; but when the time for action arrives, stop thinking and go in. One man with courage makes a majority.
Andrew Jackson

 You cannot strengthen the weak by weakening the strong. You cannot help small men by tearing down big men. You cannot help the poor by destroying the rich. You cannot lift the wage earner by pulling down the wage-payer. You cannot keep out of trouble by spending more than your income. You cannot further the brotherhood of man by inciting class hatreds. You cannot build character and courage by taking away a man’s initiative and independence. You cannot help men permanently by doing for them what they could and should do for themselves.
Abraham Lincoln

The greatest happiness of life is the conviction that we are loved – loved for ourselves, or rather, loved in spite of ourselves.
Victor Hugo

If you stop searching, you stop living, because then you’re dwelling in the past. If you’re not reaching forward to any growth or future, you might as well be dead.
Wynn Bullock

Humility is always proof of intelligence

People who make no mistakes lack boldness and the spirit of adventure. They are the brakes on the wheels of progress.

People will do anything, no matter how absurd, in order to avoid facing their own soul.
Carl G. Jung

Life is not lost by dying; life is lost minute by minute, day by dragging day, in all the thousand small uncaring ways.
Stephen Vincent Benét

The winners in life think constantly in terms of I can, I will, and I am. Losers, on the other hand, concentrate their waking thoughts on what they should have or would have done, or what they can’t do.
Dennis Waitley

True wisdom is less presuming than folly. The wise man doubteth often, and changeth his mind; the fool is obstinate, and doubteth not; he knoweth all things but his own ignorance.

There are souls in this world which have the gift of finding joy everywhere and of leaving it behind them when they go.
Frederick Faber

You’re always believing ahead of your evidence.  What was the evidence I could write a poem!  I just believed it.  The most creative thing in us is to believe in a thing.
Robert Frost

Less fear; more hope: just four little four-letter words, but when they are vividly felt as emotion, they are behavior changing, life changing, world-changing.
Lou Tice

 To be surprised, to wonder, is to begin to understand.
Jose Ortega y Gasset

You are what you believe you are.
Seve Ballesteros

Educating the mind without educating the heart is no education at all.

I’ve never met a person, I don’t care what his condition, in whom I could not see possibilities. I don’t care how much a man may consider himself a failure, I believe in him, for he can change the thing that is wrong in his life at any time he is ready and prepared to do it. Whenever he develops the desire, he can take away from his life the thing that is defeating it. The capacity for reformation and change lies within.
Preston Bradley

Without your wounds where would your power be? The very angels themselves cannot persuade the wretched and blundering children on earth as can one human being broken in the wheels of living. In love’s service, only the wounded soldiers can serve.
Thornton Wilder

God is not justice. Justice is in his nature, but love is predominant. People attach such importance to actions and their results. They do not know that above action and result is a law which can consume the fire of hell, which can dominate even if the whole world were being drowned in the flood of destruction; they do not know that the power of love is greater than any other.
Hazrat Inayat Khan

Nearly all men can stand adversity, but if you want to test a man’s character give him power.
Abraham Lincoln

Hope is not the conviction that something will turn out well, but the certainty that something makes sense, regardless of how it turns out.
Vaclav Havel

One ought never to turn one’s back on a threatened danger and try to run away from it. If you do that, you will double the danger.  But if you meet it promptly and without flinching, you will reduce the danger by half. Never run away from anything.  Never!
Winston Churchill

Treat people as if they were what they ought to be, and you help them become what they are capable of being.
Johann Wolfgang von Goethe

If I had a formula for bypassing trouble, I would not pass it round.  Trouble creates a capacity to handle it.
Oliver Wendell Holmes

Have no fear of robbers or murderers.  Such dangers are without, and are but petty. We should fear ourselves. Prejudices are the real robbers; vices the real murderers. The great dangers are within us.  What matters it what threatens our heads or our purses? Let us think only of what threatens our souls.
Victor Hugo

You never find yourself until you face the truth.
Pearl Bailey

All knowledge is the outgrowth of obedience; everything else is just information.
Watchman Nee

Man was born free, but everywhere he’s in chains.
Jean-Jacques Rousseu – 18th Century Philosopher

Freedom is about realizing that you always have the choice to start moving in any desired direction regardless of your past

Alfred Lord Tennyson

Do not promote what you can’t explain, simplify, and prove early.
Louis Pasteur

To learn is to change.  Education, whether it involves books, body, or behavior, is a process that changes the learner…  and the best learning of all involves how to learn – that is, to change.  The lifelong learner is essentially one who has learned to deal with homeostasis, simply because he or she is doing it all the time.  Lifelong learning is the special province of those who travel the path of mastery, the path that never ends.
George Leonard

Time provides no replays.
George Leonard

The real moment of success is not the moment apparent to the crowd.

God’s problem is not that God is not able to do certain things. God’s problem is that God loves. Loves complicates the life of God as it complicates every life.

The arrows [in our hearts] seem like the truest part of life, but they are not. The heart of the universe is still perfect love.
